Please,somebody,tell me how to hide/disable status/notification bar using onluWindowManager, do not using WindowManager.LayoutParams.FLAG_FULLSCREEN, AndroidManifest or something that is not WindowManager.
this worked for me, but i had to call the method every time i wanted to make sure the flag was like this
anyViewInTheLayout.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
Put this line in your activity onCreate() method above setContentView() :
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
Hope it help!
use this as a style:
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
You can do it programmatically like this:
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
More info on official pages: http://developer.android.com/training/system-ui/status.html
You can put these code in your onCreate() method of your activity:
#Override
protected void onCreate(Bundle savedInstanceState) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
} else {
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
}
}
Hope it help!

Is it possible to hide the navbar without hiding the status bar?
I've tried this in my styles's xml
<item name="android:windowFullscreen">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
and I hide de navbar like this in the activity
val decorView = window.decorView
val uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
decorView.systemUiVisibility = uiOptions
Thank you!!
Edit:
fun hideNavigationStatusBar(activity: Activity) {
activity.window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
val decorView = activity.window.decorView
val uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
decorView.systemUiVisibility = uiOptions
}
fun translucidNavigationBar(activity: Activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
val w = activity.window
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}
}
I can hide status and navigation bar with the first method and keep the status with a translucent navigation with the second, but still I can't reach to keep the status and completely hide the navigation bar.
The easiest way to solve this is in two parts, removing the navbar and then making the status bar transparent.
1 - Removing the navbar
To remove the navbar, create a new style on the styles.xml file under the values folder that inherits from Theme.AppCompat.Light.NoActionBar.
Then on the manifest.xml file change the theme of the Activity to your custom style.
With this the navbar will be removed, but the status bar will still be grayed out.
2 - Making the status bar transparent
You can follow this tutorial to make the status bar transparent: Transparent Status Bar
Or just add the following to the onCreate method of your Activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
With this you can expect an App style similar to the one in the next picture:
3 - Removing the status bar completely
To hide the status bar completely, add this on your onCreate method:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
You can read more on this at Hiding the status bar
Result:
4 - Removing the navigation Bar
You can find a solution to this at the Android Developer site Hiding the navigation bar
Basically just add this to your onCreate:
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
You can use this method:
private void setTransparentStatusBar(Activity activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
activity.getWindow().setStatusBarColor(Color.TRANSPARENT);
} else {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
}
I want to make my activity full screen with status bar on top of it like this picture:
I have used this code in manifest inside activity tag:
'android:theme="#style/Theme.AppCompat.Light.NoActionBar"'
But my view doesn't start from the status bar & it looks like this:
How can I make my activity look like the first one?
I know that the guy asking the question may have found his own solution but for the people who are still looking for a solution this is a very simple solution but one thing it has a limitation till Kitkat so a condition is added
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
Add these to your Base Application Theme in styles.xml
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
And add following attribute to your parent layout:
android:fitsSystemWindows="false"
Hope this helps.
If you dont want your "Translucent navigation" transparent, here is the code to just make transparent the status bar
In your theme:
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowTranslucentStatus">true</item>
In your activity onCreate:
Window window = getWindow();
WindowManager.LayoutParams winParams = window.getAttributes();
winParams.flags &= ~WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
window.setAttributes(winParams);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
1. Transparent Statusbar
window?.decorView?.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
window.statusBarColor = Color.TRANSPARENT
2. Transparent Statusbar & Bottomnav bar
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
);
3. Hide Statusbar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
window.insetsController?.hide(WindowInsets.Type.statusBars())
}
else {
#Suppress("DEPRECATION")
window.setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN
)
}
4. Hide Statubar & Bottomnav bar
val actionBar: ActionBar? = supportActionBar
if (actionBar != null) actionBar.hide()
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LOW_PROFILE
or View.SYSTEM_UI_FLAG_FULLSCREEN
or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION)
where to put this code ?
override fun onCreate(savedInstanceState: Bundle?) {
/* Put above code here ..... */
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_slider)
}
Note
I checked this code in Pixel 3A emulator
Maybe customise android OS not support
set styel <style name="Theme.FullScreen" parent="Theme.MaterialComponents.DayNight.NoActionBar">
To achieve something similar to this, use this:
1. Your Activity Theme
<style name="FullScreenTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowActivityTransitions">true</item>
</style>
2. There is NO NEED to add android:fitsSystemWindows property into your root layout XML file.
3. In your Activity
Add padding top to your toolbar. I am using custom toolbar, so I am adding padding to my toolbar of the height of statusbar.
toolbar.setPadding(0, getStatusBarHeight(), 0, 0)
and the function getStatusBarHeight() is added in my Utils class
fun Activity.getStatusBarHeight(): Int {
val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
return if (resourceId > 0) resources.getDimensionPixelSize(resourceId)
else Rect().apply { window.decorView.getWindowVisibleDisplayFrame(this) }.top
}
put below of code inside onCreate()
private void setStatusBarTransparent() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
View decorView = window.getDecorView();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
window.setStatusBarColor(Color.TRANSPARENT);
}
}
Try Like This
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Hope this one will help
In Kotlin just use following code in your activity, also add android:fitsSystemWindows="true" in your parent view of activity.xml layout file.
This will also show content over navigation bar too, provided you declared full screen style in your style.xml
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
}
you can use this code after onCreate
setTheme(android.R.style.Theme_Black_NoTitleBar_Fullscreen);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
if (getSupportActionBar() != null) {
getSupportActionBar().hide();
}
your activity will be fullscrean with status bar :)
#tahsinRupam answer is correct and tested on post Kitkat version.
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
If you want to use it only for a certain activity, create a style, and attach it on your manifest style like this.
<activity
android:name=".MainActivity"
android:screenOrientation="portrait"
android:theme="#style/Activity.Fullscreen.Theme" />
<style name="Activity.Fullscreen.Theme" parent="MyMaterialTheme.Base">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
Thumbs up on origal #tahsinRupam
Happy codings Cheers !
Put this code in your Activity onCreate this will hide the status bar
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();
I want to hide status bar / notification bar in splash screen I am using
style:<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
this dose not hide the status bar, how should i do this?
If you want to remove status bar then use this before setContentView(layout) in onCreateView method
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);

You can do something like below for appropriately setting theme on your particular activity -
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowBackground">#drawable/launch_theme</item>
<item name="android:windowTranslucentNavigation">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
</style>
Try this:
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
<item name="android:windowFullscreen">true</item>
</style>
Use Below Code to solve your problem.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Add Below line to hide
getSupportActionBar().hide();
}
Try this complete solution for backward below android version 16 and forward compatible solution
if (Build.VERSION.SDK_INT < 16)
{
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else
{
View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
For Kotlin users.
In styles.xml add new style:
<style name="NoActionBarTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
Now in AndroidManifest.xml add newly created style:
<activity
android:name=".MainActivity"
android:theme="#style/NoActionBarTheme"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustResize"
>...</activity>
Finally in MainActivity.kt make following changes:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
//Add below line to hide status bar
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN
}
Now the status bar should be gone:
To make your activity fullscreen, add this code in onCreate before setContentView:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
This is what I used and it worked perfectly.
Add this code to your activity onCreate before setContentView:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
if you are using this in theme app
Theme.MaterialComponents.NoActionBar
change to
Theme.AppCompat.NoActionBar
and add code in activity:
fun fullScreen(activity: Activity) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
if (activity.window.insetsController != null) {
val insetsController = activity.window.insetsController
if (insetsController != null) {
insetsController.hide(WindowInsets.Type.statusBars() or WindowInsets.Type.navigationBars())
insetsController.systemBarsBehavior =
WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
}
}
} else {
activity.window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
}
}
If you want to hide status bar line and action bar, you have to change the line in themes.xml
<style name="Theme.MyApp"
parent="Theme.MaterialComponents.DayNight.DarkActionBar">
to
<style name="Theme.MyApp"
parent="Theme.MaterialComponents.DayNight.NoActionBar">
and this to activity class in which you don't want status bar line..
requestWindowFeature(Window.FEATURE_NO_TITLE)
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
Plz make sure that you have to add these lines above this in onCreate() method.
setContentView(R.layout.activity_main)
Try this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
I did some magic code. Buttons in the status bar can be clicked, but it's difficult. Part for 4.4 does not work well.
/** Скрывает статус-бар */
private void hideStatusBar(View decorView)
{
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
android.app.ActionBar actionBar = getActionBar();
if (actionBar != null)
actionBar.hide();
}
#Override protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
try
{
// for < 4.0
if (Build.VERSION.SDK_INT < 16)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
// for > 4.0
else
{
final View decorView = getWindow().getDecorView();
hideStatusBar(decorView);
decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener()
{
#Override public void onSystemUiVisibilityChange(int visibility)
{
if (visibility != View.SYSTEM_UI_FLAG_FULLSCREEN)
hideStatusBar(decorView);
}
});
}
}
catch (Throwable t)
{
Util.log("Ошибка при попытке свернуть статус бар");
t.printStackTrace();
}
setContentView(R.layout.activity_main);
}
If you want to remove the status bar then
For Java
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
For Kotlin
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN
For flutter
SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]);
I have an activity that goes to another full screen activity. However, when transitioning from this activity to my full screen activity, the navigation bar slides down instead of disappearing instantly. I've inflated a full-screen window in the second activity, but because of the slow sliding animation, it resizes 1 second later after the animation has completed instead of being inflated to full-screen immediately. Therefore, I need the animation to disappear instantly. I've tried
<item name="android:windowAnimationStyle">#null</item>
and
overridePendingTransition(0, 0);
and
Transition fade = new Fade();
fade.excludeTarget(android.R.id.navigationBarBackground, true);
getWindow().setEnterTransition(fade);
with no luck.
On the Windows side, I've tried
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
WindowManager.LayoutParams.FLAG_FULLSCREEN
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
How I hide the navbar: View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
I think, I nailed it:
FullscreenActivity class:
public class FullscreenActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
decorView.setSystemUiVisibility(uiOptions);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.hide();
}
setContentView(R.layout.activity_fullscreen);
}
}
Manifest:
<activity
android:name=".FullscreenActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="#string/title_activity_fullscreen"
android:theme="#style/FullscreenTheme"/>
Styles:
<style name="FullscreenTheme" parent="AppTheme">
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:actionBarStyle">#style/FullscreenActionBarStyle</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowBackground">#null</item>
<item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
<item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
</style>
NB! Setting StatusBar colour required API 21. For the older versions, to "hide" StatusBar, you need use:
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN;
as uiOptions in the code above. (it'll cause quite quick resizing, though).
I hope, it helps
I have an android app which uses immersive mode for all activities - so its a full fullscreen app.
I have a BaseActivity class from which all other activities extend. In this activity I call the following to enable fullscreen/immersive
HelmiBlankActivity:
private boolean apiLowerImmersive = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
apiLowerImmersive = true;
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
}
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if(hasFocus && !apiLowerImmersive ) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}
}
In activities it works great, the problem is: When opening a new activity (per intent) the actionbar/titlebar are displayed for a short time and then hidden again - which seems kind of laggy/buggy.
The Application also has a theme:
styles.xml:
<style name="FullscreenTheme" parent="android:Theme.Holo.Light">
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
I have tried applying the android:Theme.Holo.Light.NoActionBar as well - no success during transitions.
I could not find anything on stackoverflow (which btw is a great community and has helped me with many problems) or anywhere else on the internet and would appreciate your help.
If you put this snippet into onCreate() method your activities will open with the bars already hidden.
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE);
You can also add conditions for older SDKs. The only problem I've got with this setup is the fact that once i swipe down to show bars, they won't hide again...
